In the forni of the device iustrated inA Figs. and 10, vwhen in position and opera-l trated in Figs. 2 and 10, it is shown as pisv ton 11,1novable in a cylinder in communicetioii with the chamber 1, S0 that the -fluid piston, though entirely independent and freev to move in response to heat vpressure impulse, is also iinder control as to its po sition. Power connections fate represented by a'rock-shaft 12, with levers to operate piston 11 and the various valves for controlling the charges "and effecting the ignition.

As illustrated in F ig. 2 the piston 11 is provided with a rod 13 which extends through a stuffing-box 14 in the side of the device. The rod 13 in this form is connected to a motor cylinder 15 by suitable connections such as links 16, levers l?, rockshaft 12, link 18 and the piston rod 19 as illustrated in the forms either Fig. l0 or Fig. 7. A pi e 2O forms an outlet for the chamber or ciambers 8.v The chambers 8, if. more than one, may be connected so as to form one air chamber of large size compared with the volunie of the water-piston. In other words the piston should always be of relatively small size as compared with the resilient cushion of Ithe air chamber..

'lo operate in propel' sequence the .other working or controlling devices, I have provided'tlie following described mechanism.

A cani lever and tappet 21 is attached securely on shaft A12 having cam vsui-faces 21L und 21. A plug valve 22 is common to and controls the flow of gases to or from the two explosion chambers. It is shown connected 'to the explosion chamber in Figs. 3, -l, '5 and 10, by pipe 23. A check valve 24, controlling the admission of the explosive charge, is provided with a spring actuated valve stem 25, as shown in Fig. 5. The operating lever or handle 22'a is secured to the plug or stein of the valve 22. A slotted link 22.h is loosely connected to 22 and engages with one arm of a loosely pivoted hellci-ank ft'appet lever 22e. The other arm of the le- `.ve'r 22c constitutes a tappet which engages with the part 2la of the cam ended lever 2l to operated thereby at each are reciprocation of the cam end ofthe lever. This cam end serves the double function of re-V versingpthe four-way valve 22 and raising and keeping the valve 24 open, by engagefaceted to a `fuel reservoir 27 hy valve controlled pipeliigs. it

The other element of the sparking device consists of a flat spring 33 attached to an insulated rod 34 passing to the outside of theignition chamber.

35 isa tappet lever secured upon tht)l spindle of each of the valves 10.

is a link slotted at each end for the reception of the pin 37 on the ta pet levers 35. The' link 3G is provided wit a pin 38 approximately midu'ay of its length, which .engages with the leverri32 of the spark wiper, Figs. 4: and 5. suitable source ofelectrical energy is reprelsented. by 39. i

A battery or other 40 and 41 are wires leading to the wiper and spring respectively. A yoke .al-2 is secur'ed upon lthe piston-rod 13 and its ends are iivotallv connected to the rods 1.6 Figs.

Aiplug valve 43 is placed in a pipe 4:4

which connects' the opposite ends of -cylin- 100 der 15, see Fig. 7, and a pipe 45 connects the valve and the cylinder ends with a source` of pressure through pipe 20. An exhaust pipe `for the four-way valve43 is shown at 46 which permits each end of 105 cylinder 15 to exhaust alternately. ,An operating lever 4-7 is provided for valve 43, which is connected to a sliding tappet rod L8 having springs 49.y and tappets 50.

Levers 5l, hinged at endend and each pro- 110 vided, at oi near that end with a cam sur face 52, are provided. The opposite end of each lever is vprovided with a wedge-shaped latch, toengage with tappets 50. A tappet 53 is secured upon one of the rods 16, to 115 engage with and release the latch levers 51' alternately. All of which is clearly shown inl Fig. 7.

In Fig. 10 is shown a complete operative unit or single cylinder device: All theworking parts are in oierative nssociation.
